The virus was detected in 24 species and a solanaceous weed Solanum nigrum . Of these, the following 17 species are being reported for the first time as hosts of the virus in...

Context Studies of Phoma black stem and leaf spot disease (caused by medicaginis) in annual medics (Medicago spp.) normally involve a ‘once-only’ inoculation not reflecting multiple pathogen infection phytoestrogen production cycles the field. Phytoestrogen plants can result lower ovulation rates grazing animals. Aims We aimed to determine whether sequential infections P. medicaginis increase p...

Phoma black stem and leaf spot disease (Phoma medicaginis) not only destroys annual Medicago spp. forage seed yield but also reduces herbage quality by consequent phytoestrogen production that ovulation of grazing animals. Two controlled environment studies evaluated the effects plant developmental stage in rugosa ‘Paraponto’ M. scutellata ‘Sava’ different inoculum concentrations P. medicaginis...
